Optimalizace navrhu technickych protieroznich opatreni

摘要

Souhrn V CR je více jak polovina uzemi ohrozena vodni erozi. V dusledku predpokládanych klimatickych změn se projevi zvysenym vyskytem extremnich situaci. Je tedy úcelne hledat zpusoby lepsiho hospoda-rení s vodnimi zdroji, resit ochranu intravilanu a zajistit trvalou udrzitelnost krajiny (predevsim ochranou vody a pudy). V clanku jsou predstaveny vysledky z projektu ,,Optimalizace postupu navrho-vani technickych protieroznich opatreni". Cilem je provest inventari-zaci existujicich a planovanych technickych protieroznich opatfeni v CR. Inventarizace je podkladem pro kategorizaci protieroznich opatfeni technickeho charakteru (TPEO). Poznatky z inventarizace poslouzi k vyjadfeni k ochrannemu ucinku TPEO z hlediska snizeni ztrat pudy erozi, velikosti povrchoveho odtoku a nakladovosti na jejich vystavbu, vcetne moznosti jejich vyuziti k zlepseni stavu krajiny a ochrany pfirody. Soucasti feseni je i vyber vhodnych vypocetnich nastroju a metod hodnoceni eroze a navrhovani TPEO, vcetne posouzeni aplikovatelnosti a zpracovani postupu pouziti vhodnych nastroju pro ruzna měrítka a rozsahy reseni a doporuceni metod i konkretnich prvku TPEO pro regiony CR.%More than half of the area of Czech Republic (CR) is threatened by water erosion. The expected climatic changes will result in the increase of extreme situations. It is therefore advisable to seek ways for better water recourse management, to protect urban areas and to ensure sustainability of the landscape (especially water and soil conservation). This article presents the results of the project ,,Optimi-zation of process designing technical erosion control measures". The aim is to make an inventory of existing and planned technical erosion control measures in the country. Knowledge of inventory will be used to explain a protective effect of TECM to reduce soil loss by erosion, surface runoff and extent of constructions cost, including their use to improve the landscape conditions and nature conservation. The solution is the choice of appropriate computational tools and methods for designing erosion and TECM, including the applicability of the assessment and treatment procedures using appropriate tools for different scales and ranges of solutions and recommendations of specific methods and elements for TECM regions of the CR.
